IMPROVEMENT. IN WATER-CLOSET VALVES.

Specification forming partof Letters Patent No. 177,023ydated May 2, 1876; application led March I3, 1876. I l

To all whom it may concern;

Be it known that I, WILLIAM SMITH, of San Francisco, State of California, have inv vented an Improved Valve for Water-Closets, of' which lthe following is a specification: o.

My=inventionrelates to thatl class ofwaterclosetvalves, constructed with the object of automatically shuttingfofl' the supply of water to the receiver within a certainl time, to 'prevent wasteful use, and .of controlling the amount of water admitted to the hopper or receiver.

It consists, mainly, in the construction of a piston or plunger of peculiar shape, upon the areaof whose face a pressure of water is caused to impinge, whenthe valve is opened, for theo-purpose of automatically closing it and shutting olf the supply at the proper time without the use of a spring; also, in combination with such vplunger in a Waterclosetfvalve,tl1e arrangement of mechanism for governing the action of the piston, and for adjusting the supply of water to the receiver according to the pressure, as will hereinafter be more fully described.

Figure lis a front elevation of my improved valve and a portion of the receiver in section. Fig. 2 is a side elevation' ofthe valve andthe chamber that connects it with the receiver, the outer shell of the valve and the loweruportion of the plunger being shown in section. Fig. 3 is a' view of the plunger and its reliefpiston removed from the valve.l

A represents the outer shell of the valve; B, the plunger; C, the spindle,l and D the auxiliary plunger. E is the relief-piston, and F G are annular exible washers, the lower one, F, acting as a valve to govern the adymission of the water to the chamber H. I is ber'attached to the side of the receiver X having a screw-thread opening to receive the end ofV the valve-body, and an inlet into the' side of the receiver to allow the drippings from the valve to pass4 off. O is the lever, with an arm, P, for raising the valve from its Seat. The valve-shell has a chamber, H, at

. lits upper end, and a similar one at thelowery lend, but the upper one is made airtight by means of the flexible washers -F Gand the water-pressure from-below. while the ,lower` one opens into theehamber N. Betweenl these two chambers vis situated the valve-seatI.

The valve or plungerB moves` up and down 1` i.

Within the chamber above the valve-seat, and

its upper end has a piston, E, of smallerjdiamcter than the plunger, that Works through The an opening in the top ofthe chamber. upperpart of the valve B and Athe pistonE thus move withina chamber' that. is ymade air-i tight by the arrangement-of the flexible washers G that` surround lthe upper part of the piston, and the body of the plunger or valve B Works through'an annular Washer, F, that y operates as a valve to governfthe flow of water-into and out of this chamber H. The valve-spindle C carries an auxiliary plunger, D, that moves freely Within the chamberY at l vthe bottom ofthe valve-body.. The end of thespindle, whenfthe valve B kis down upon,- its seat, rests upon the arm P of `the lever O.y within the chamber N4, as shown by thedotted y linesin Fig. 1. .The area :of the face'of the auxiliary-plunger is somewhat .largerthan the 'face of the plunger .-B- above it, and .thetwo Y being secured to the same spindle, it follows that, when the valve is raised from its seat I to admit the water, the auxiliary plunger rises toward this opening. The incoming stream of water in passing through the valveopening thus meets and impinges upon the face of the plunger D, but it likewise presses against the face of the valve or plunger proper B; but the area of the face of the auxiliary plunger D is larger than the area of the valve B, so that the pressure of' the water tends to move the plunger D away from the valve-seat I When'the lever O is dropped, and thus bring the valve AB down and shut off the water.

By this construction every time the lever 0 is lifted the valve is lifted, and when the lever is dropped the force of thel Water tends to close the valve in a gradual and regular 2 i ifndef:

iiange onthe chamber N, and the vother end is connected to the rod and handle for operating it. The lever has an arm, P, of such form as to extend beneath the end ot' the valve-4 spindle G,'and thus' raise the valve when the handle 'is pulled.y fr r The chamber N is made to'catch the drip from'the valve. It is provided with an outlet-vv leading into the receiver X, to allow the'E waste .water to 'run oftlf It has a ilange for secnringit to the side `of the receiver, as

shownsin'Figs. 1 and2, sorthat it serves both as a support for the valve A and. asa i drip: chamber to .catch `thewaste due to the wear and leakage of the* parts.` i The means `for Vgraduating :the size of ,the stream of water through the outlet to;

i ``:the receiver X consist of a'screwespindle; It,`

movable withina` socket, S, and provided with .a circular head,` M, somewhat smaller, than #th'e'mouth ofthe outlet L. Y Thishead isv adjusted by means of the nut Ufupon the outi side 'of` the pipe L, and `by being set more or less within. the orifice of the outlet, the size of the opening is contracted, as the water is obliged to pass out between the head M and the r'im of the orifice' in the discharge-pipe.

This regulator is.` used to adjust the size of the stream of water flowing into the receiver X according to the pressure of the water admitted through the valve, and this pressure varies with the position of the closet y and the proximity of other receivers.

This arrangement valve mz'tyibelals'ohsedff` with self-acting water-closets where the valve is operated by the pressure or weight thrown upon the seat when in use, but in such ease the valve A should be reversed, so that Vthe spindle C will be uppermost, in order tohave the vpressure from above to open vthe valve.

The' auxiliary plunger D will then require a watertight packingl similar to the washers G that surround the piston E. i

Having thus fully described luy-invention, I claim `therein as new- 1. Ina valve for water-closets, the relief.

piston E attached to the water-valve B, and.
